Beer Can Dust Cap for Trailer Hub & Bearings

Using a Beer Can as a Dust Cap for Your Trailer

Easy installation of a beer can over your trailer hub. This will keep your bearings clean and in good condition.

The Beer can has yet another great use to save you time and money. It just so happens that a beer can will fit right over the top of most trailer hubs. These are used to keep dirt and dust out of your bearings. If you get sand and dirt in your bearings, your trailer will inevitably have a blowout. This is never a fun situation. About 2 years ago I was traveling across the country with my boat attached. When I got to central Wyoming I saw that my dust cap had slid off. I neglected to fix it for just a couple hours and the centrifugal force had caused all of my bearing grease to fly out the hub. This causes the bearings to get to hot, overheat and inevitably fail. Had I stopped at a rest stop and done this beer can trick, I would have saved myself hours and hours of trouble and a lot of money. The small repair shop I went to charged me hundreds of dollars for a bearing installation. I had also done some damage to the axle. The repair shop didn’t have any dust caps in stock. I pulled away a few blocks from the musty garage, stopped and installed some beer can dust caps. They have been there ever since. I took this image today as I was about to inspect my bearings for another long trip across the US.
